A matched pairs experiment yielded the following results:
Number of positive differences = 20,
Number of negative differences = 8
Number of zero differences = 2
Can we infer at the 5% significance level that the location of population 1 is to the right of the location of population 2?
Test statistic:
z-statistic = ______________
Rejection region:
Reject if the z-statistic ______________.
Conclusion: ______________
We ______________ infer at the 5% significance level that the location of population 1 is to the right of the location of population 2.
